Title: Improvements in and relating to the control of reversible self-starting single phase motors
IPC: H02P1/12
Filed: 1956-03-29
Abstract: 790,730. Control of A.C. motors. GENERAL ELECTRIC CO. March 29, 1956 [March 29, 1955], No. 9863/56. Class 38 (3). A single-phase motor having a reversible starting winding 6 and running windings 4, 5, adapted for lower and higher speed operation alternatively, is started in one direction by connecting switch 29 to a low-speed contact 31 and moving switch 11 to engage contacts 15, 16, 17. Relay coil 37 is then connected for energization in series with the main low-speed winding 4 whereby contacts 40, 41 are actuated to engage contacts 51, 55, respectively. A circuit is also established through centrifugal switch 45 to capacitor 8 and starting winding 6 so that the motor begins to rotate. At a predetermined speed, switch 45 moves to engage contact 53 to disconnect the starting winding, but the winding 4 is maintained energized, however, through contact 40. When switch 11 is thrown to its reverse position, relay coil 37 is de-energized and contact 40 is spring-urged to engage contact 56. Windings 4 and 6 are connected in a loop circuit for braking until the speed drops sufficiently to allow switch 45 to return to the position shown. The motor then starts in the reverse direction since the connections to the starting winding have been changed-over by the switch 11. If the switch 29 is actuated to engage the contact 30 whilst the motor is in operation, a direct change to high-speed running is effected. When high-speed operation is desired and the motor is at standstill, a circuit is completed from contact 30 through relay coil 33 and winding 4, and the motor starts in the same manner as for low-speed operation. When the cut-out speed of the centrifugal switch is reached, windings 4, 6, are de-energized and winding 5 is connected in circuit. Actuation of switch 11 to its reverse position establishes a braking loop circuit including windings 4 and 6, after which the motor is started in the reverse direction. In a modification, the relay 38 is replaced by one having a single coil and a selector switch is connected to one side of this coil, the other side being joined directly to the line, Fig. 2 (not shown).
